title: Isolated high lateral acute myocardial infarction with superior injury current axis.
abstract: We report a 70-year-old man with high lateral ST elevation myocardial infarction secondary to occlusion of left circumflex artery. Electrocardiography (ECG) showed ST depression in inferior leads and isolated ST elevation in leads aVR and aVL, demonstrating a superior axis of the injury current vector. Different presentations of ECG pattern from left circumflex artery occlusion were discussed. This case highlights the importance of recognising unusual ECG pattern in accurate diagnosis of acute myocardial infarction.
